GRUBMAN METHOD AND MEANS FOR MILLING EYE SOCKETS IN DOLL HEADS Filed March 1, 1927 3 Sheets-Sheet is. 5110*" 'NEY horizontal or a vertical Patented Sept. 23, 1930 (UNITE- T E P AI F LEOJ.GRUBMAN, 0F'IBELLE ma nate, YoaK METHOD AND MEANS'FOR MILLING nYn socKE'rs IN DOLL HEADS Application filed March This invention relates Y to an improved methodand means for milling eye sockets in} doll heads, and has for its primary object toprovide a method whereby the eye member receiving sockets may be accurately formed after the doll head has been completely closed with, the exception of the neck opening and which substantially eliminates all possibility. of-human error and insures a symmetrical curvature of theeye socketwalls with respect to the upper and lower edges of the individual eye openings as well as correspondence in the relationship between one socket and eye opening with the other. To

.- this end, the new method consists essentially in operatively arranging a milling cutter through the neck of a doll head for bodily shifting movement to positions in cutting engagement with the doll head wall; in accu rately centered relation to the respective eye openings, and-supporting the doll head for movement in a single direction as the cutting action progresses while positively preventing turning movement of said head in eithera to'the milling cutter.

It is another important object of the invention to provide a simply constructed means for operatively mounting or supporting the milling cutter whereby the cutter may bebodily moved aboutan imaginary fulcrum or point located in a plane inter- ,secting its axis of rotation to position the cutter'in definite operative relation to the spaced eyeopenings in the doll head wall.

It is another object of the invention to provide as an important part of the apparatus a means adapted to cooperate with means internally formed on the wall of the doll, head which prevents any turning or bodily movement of the doll head with re spect to the milling cutter but permitsof its angular movement in one direction to main tain uniform pressure of the doll head wall at the upper and lower edges of the eye opening therein against the milling cutter as the cutting action progresses.

A In'a practical embodiment of the invention, I providev a rotatably mounted support for the milling cutter and an operating I plane with respect one simple and practical embodiment of the 1927. Serial No. 171,769,

motor therefor, the spindle of the milling cutter being positioned at an oblique inclinati'on andin'tersecting theextended axial center line ofthe' support so that upon the rotation of said support, the'cutter maybe moved about the imaginaryfulcrum located at 'said point of intersection and po'sitioned at either sideoi said center line.' v

It is a further generalobjectot theinvention to providea-machine or apparatus having the above noted characteristics which will be efficient in its operation, and in which the several parts are of simple construction and compactly mounted and arranged and in l the operation of which special skill on the part of the mechanic is not required.

l/Vith' the above and other objects in view, the invention consists in the improved method and means for milling eye sockets in doll heads, and in the several novel features of the disclosed apparatus, as will be hereinafterv more fully described, illustrated in the accompanying drawings, and subsequently incorporated in the subjoined claims.

In thedrawings, wherein I have illustrated taken on the lined-450i Fig. 1.

Referringin detail to the drawings, the

operative parts ofthe apparatus are mounted upon an obliquely inclined arm 6 integrally formed with a suitable base 5 which is adapted to beibolted, clamped or otherwise fixedly secured: upon a work bench, table, or other support. I a v in an. opening 7 provided in the arm 6, a supporting means for the milling tool and its operating motor is rotatably mounted.

This supportingzmeans, as herein shown inclndes a disc 8 snugly fitting" in the opening '5 and hay ng an outwardly prqecting angular flange 9 extending upon a suitably formed seat 10 on the upper surface of the arm 6. A lower disc'll is rotatably engaged with the under sideof the arm 6 and is pro vided with a radially extending groove or key-Way indicated at 12 to receive a locking rib or key 1 formedupon the plate 13 extending across theunder side of the disc 11.

The discs 8 and 11 are rigidly connected with each other by the screw 15 which also is preferably threaded into a bore or socket in the end of theplate 13 asshown at 16 inFig. 1 of the drawing. A second screw 17 is also engaged through registeringopenings in the plate 13 and disc 11 and is threaded upwardly into the disc 8. p y

Upon one end of the plate 13, a downwardly extending obliquely inclined'arm 18' isformed and upon thelower end of said arm the operating motor 19 for the spindle 20 of the" milling jcu'tter 21 is suitably mounted. The spindlej20 extending through the elongatedbearingextension 22. on the upper end of the motor casing has its axis positioned in substantially parallel relation with the arm 18,-and it will therefore, be understood ferably provide upon the arm 18 and below the plane of the plate 13, a suitably formed weight 26.

i At the opposite side of the motor 19, the

end 'of the plate 13 is extended to form a suitable handle 27 by means of which the two discs 8 and 11 together with the operating motor may be rotated as a unit upon the arm 6; This rotation of the supporting lmeans for the vmilling cutter is definitely limited in each direction by means of the so.

adjustable stop screws 28 which are threaded inthe lugs 29 on the under side of the arm 6' at opposite sides of the rotatable support. The plate 13 is formed with an upstanding 111g 30 which is adapted for contact with the ends of these adjustable stop screws as seen in Fig. 2 of the drawings.

' Upon the upper end of'the inclined arm 6, the lower'end of a bracket member 31 is rigidly fixed. This bracket member has an intermediate angularly disposed portion 32 positioned in a plane substantiallyparallel wlth the plane of the arm 6 and having an opening 33 therein through which the milling cutter spindle 20 extends. To theupper "end of-the bracket member3 1 an arcuately "spindle curved or crescent shaped plate 34 is fixedly secured at its center, the outer edge of said plate at the ends thereof being inwardly beveled or inclined as indicated at 35.

The doll head as shown at D is provided -with the usual spaced eye openings at in its front wall and each side wall of the doll head is internally formed with a horizontally extending groove d, the said grooves being located in accurate relation to the centers of the eye openings d. The base walls of these grooves are obliquely inclined in substantial conformity to the inclined edges of the plate 34:. 7

In the use of the apparatus above described, the doll head is arranged over the milling cutter 21 and the upper end of the 21 and the upper portion of the bracket 31, the said parts passing easily through the neck opening of the doll head. The doll head is manipulated until, by the sense of touch and observing one end of the plate 34 through one of the eye openings 11, the ends of said plate are positioned in the grooves on the opposite sides of the doll head wall. Upon moving the handle 27 in one direction to engage the lug'30 against one of the. stop screws '28, the milling cutter 21 will be positioned with its geometrical center disposed in a plane which intersects the center of one of the eye openings cl and with said cutter in contact with the inner surface of the front wall of the head'at the edges of said eye opening. The motor 19 is then set in operation so that the tool 21 will rapidly mill or cut out the material of the doll head wall at the inner side thereof, said cutter being of spherical form producing a concave socket in said wall. The operator has only to maintain a light pressure upon the outer side of the front wall of the doll head to hold thesame in contact with the tool as the cutting action progresses. Owing to the fact that the ends of the plate 34 are snugly engaged in the grooves 35 on the side walls x of the doll head, there is no possibility of the head turning or rotating bodily in either a horizontal or a vertical plane about the axis of the cutter 21. Therefore, it is not possible for the operator,even'intentionally to produce a greater pressure'of the head wall upon the cutting tool at one edge of the eye opening (Z than at the other edge thereof. Accordingly, the curvature of the wall of the sock'et'will be symmetrical with respect to the '1 upper and lower edges of the eye opening. Therefore, when an oscillatory eye member is subsequently mounted in the eye socket, the pupil thereon will'movev in accurate relation with respect to the edges of the'eye open- 'ing in the opening and closing movements of the eye member and the free non-binding oscillatory motion ,of the eye member is also assured. After one eye socket has thus been milled, the operator then moves the lever handle 27"to r otate the cutting tool and its operating motor through a path of substan-' tially 180 until the lug 30 abuts against the other stop screw 28. In this rotation of the tool support, it is obvious that since the axis drawings. By the proper adjustment of the stop screws 28, this turning movement of the spindle support is definitely limited in accordance with the known distance between the centers of: the eye openingsd inthe doll T head. Thus, withoutremoving the doll head D from its supported position on the ends of the plate 34, the cutting tool 21, aft'erhaving milled out one of the sockets may be quickly positioned in accurately centered relation to the OllllBF'Of the eye openings. The motor 19 is then again operated to mill out the socket at the inner side'of the latter opening. The operator by observing the relation between a point on the cutting tool 21 and the edge of the eye opening at the outer surface of the head wall insures the cutting or'milling of the two sockets to the same diameter. Thus,

the relationship between the curved wall of the socket and one of the eye openings will accurately correspond with the relationship between the other eye opening and the wall of the socket associated therewith.

The apparatus abovedescribed may be employed for the milling of the eye sockets in doll heads of different sizes, it being only necessary to select the plate 34 of the proper width and to adjust the stop screws 28 so as to limit the bodily movement of the milling cutter in accordance with the spacing between the centers of the eye openings in the particular doll head. It will be apparent that my new method and apparatus for milling the eye member receiving sockets assures absolute uniformity'iu the product so that eye settings designed for application to heads of a certain size will be interchangeable with other doll heads of the same size. ,It will also be seen that I accomplish this desirable result by mechanical means which is of. very simple construction and which insures the greatest accuracy without necessitating a high degree of skill on the part ofthe mechanic. In certain co-pending patent applications, I have disclosed difilerent devices for milling the eye receiving sockets in doll'heads, and in one of these prior embodiments, two separate spindles are provided to simultaneously operate upon the doll head wall whil in another instance, I have disclosed a single milling cutter. In each of these cases however, it

is necessary to use a gauge orgsighting means and reliance must be placedto a certain eritent upon'the skill of the workman in properly adjusting and positioning the doll head with respectto this sighting means. There fore, in the present instance, by eliminating such gauge devices and reducing thepossibilityof a human error to a minimum, I se-' cure greater uniformity in the product. Also, since the present". apparatus may be operated with g eat rapidity there is no appreciable reduetionin the quantity production of the product. a

In the accompanying drawings, I-have illustrate'd anembodiment of the machine or apparatus, which has produced excellent results inpractice. Nevertheless, in so far as my new method and the essential features of the disclosed apparatus are concerned, the same might be exemplified in numerous other alternative structural forms, and I accord-- ingly reserve'the privilege of resorting all such legitimate changes the-rein'as maybe fairly embodied within the spirit and scope or the invention as claimed. 1
